Isabelle & Max wall decals arrive safely and securely packed in a protective bag and box. The decals come with full installation instructions that are easy to follow. Isabelle & Max wall decals work the same way as professional-grade decals used in the automotive and signage industries. Application is easy and does not require professional experience. Having a helper while applying the large Birch Tree decals will make the application faster due to the large size of the decal but even one person can apply this life-like scale decal. Even though the decal uses a strong adhesive that is meant to last for years and years, the decal can be removed at any time by slowly peeling the decal off the wall. The decals will not leave any residue and will not damage the wall and paint as long as the paint is in good condition.
